Problem: An alpha particle (mass = 6.6 x 10 −24 g) emitted by a radium isotope travels at 3.4 x 107 ± 0.1 x 10 7 mi/h. What is its de Broglie wavelength (in meters)?

FREE Expert Solution

The de Broglie equation is an equation used to describe the wave properties of matter. The de Broglie equation is as follows:

Where λ is the wavelength of the particle (m),

            is the Plank’s constant (6.626 x 10-34 mkg / s)

            m is the mass of the particle (kg)

            is the speed of the particle (m/s)
